PROBLEM TO BE SOLVED: To provide an attachment structure of a vehicle seat which uses a simple structure to inhibit rupture and deformation of a seat attachment part and a surround area of the sheet attachment part.SOLUTION: A tunnel shaped backbone 6, which extends in a vehicle fore-and-aft direction, is formed in a vehicle width direction center part of the floor pan 1. Seat brackets 2 for supporting a vehicle cabin center side fixing area of the vehicle seat 10 are joined to the backbone 6 at the upper surface side of the floor pan 1. Additionally, reinforcement members 4 for reinforcing the fixing area are joined to positions at the lower surface side of the floor pan 1 which face the seat brackets 2. Further, curve surfaces 5 which curve toward a direction that moves away from the floor pan 1 are formed at end edges of each joint surface of the reinforcement member 4 and the floor pan 1. |
